I am doing a project in which i am required to create GTFS. I look at transit google developer forum which provide a format to create feed but that completely have to done by hand (we have to write text files), i was looking for a software that can help in this matter.

Another option is the service provided by AddTransit (http://addtransit.com), of which I am the manager of.

AddTransit has web based software that assists in creating the GTFS Feeds or the AddTransit team can do it for you. The web based software also supports Real Time feeds and vehicle positioning as well.

In cases like this it might be best to give full disclosure if you are an employee of or otherwise professionally connected to the software/service you are recommending. Nothing wrong with it if you are, but it helps distinguish such an answer from 'advertisement'.
